[The praise of the leak: a tribute to Henri Laborit (1914-1995)].

Henri Laborit (1914-1995) was a French military MD. He contributed to the discovery of an important molecule that has changed the face of psychiatry, namely chlorpromazine, which became the first drug in the class of first-generation antipsychotics, which later led to the dopamine hypothesis of schizophrenia. He did not receive the Nobel Prize for this discovery, unlike Daniel Bovet who get the Nobel Prize for the discovery of antihistaminics. Henri Laborit is also the author of a book that has contributed to the popularization of neurosciences in France, "The Praise of flight" (1976).
